I think your poll results depend entirely on the employer, the employee's history and their attitudes. It would be very difficult to base job satisfaction on pure statistic, especially as people and their situations can be so unique.

However, for what it may be worth:
Being a helpdesk pro has always been quite stressful for me, but I've now developed a much more efficient way of handling stress.
My job title greatly undercompliments my job roles and what is expected of me is most certainly not worth the pittence I receive.
But I'm trying hard to believe that my efforts will be recognised and I will be developed to a new role and title, or at least appreciated by the employer.
That said, I am personally quite content in my job role and receive much praise from colleagues. The job is secure and forseeably so.

To close, there is most certainly a much less fortuante situation out there, should a choice be presented.
